Unique Premise from a Hamster's Point of View
Sweet Hamster Days takes players into a fairly unusual story. The main character is Kota Kurono, a man who returns to his hometown to meet the three Shiratori sisters, his childhood friends. However, after a traffic incident, he wakes up in the form of a hamster.
As a pet hamster named Hamta, Kota now lives with the three sisters. The game invites players to see their lives through the eyes of a pet. While the story is lighthearted and cute, it also carries an element of mystery about the sisters' relationship that is no longer as warm as it once was.
Three Shiratori Sisters at the Center of the Story
Story Sweet Hamster Days focuses on Himari, Futaba, and Miyu Shiratori. Himari is the eldest sister who works as a consultant and is known to be reliable at work. At home, she has a more relaxed side and is close to Hamta.
Futaba is the middle sister who is in college and looking for a job. She is described as serious, diligent, and has a background in ballet since childhood. Meanwhile, Miyu is the youngest sister who is still in school and is talented in music, especially the saxophone.
Through their interactions as hamsters, players will help uncover the problems they are facing. The story also attempts to answer what happened over the past six years to change the trio's relationship.
Live-Action Format and Language Support
This game uses a live-action FMV format instead of 2D illustrations like many other dating sims. The scenes in the game are presented in 4K video, so the gaming experience feels closer to an interactive drama.
Sweet Hamster Days will support several language options, namely English, Japanese, Traditional Chinese and Simplified Chinese. This language support makes the game more accessible to players from different regions.
The game also involves several Japanese cast members, namely Sayaka Tomaru as Himari, Momoha Takatsuru as Futaba, and Shiori Ikemoto as Miyu.
